SPECIFICATION fomingpart or Letters ratent Ivo. 591,075, dated october 5, 1897.

Application led January 2, 1897.

To all whom it may concern/r Be it known that I,` GEORGE B. GATES, a citizen of the United States, residing at Lynn, in the county of Essex and State of Massachusetts, have invented certain new and useful Improvements in Beating-Out Machines,

of which the following is a specification.

My invention relates to machines for beating out the soles of boots and shoes, and more particularly to means for automatically moving to the front of the machine and back again the slide which in the type of machine to which my improvement is applied carries the shoe-supporting jack.

My invention is more especially intended to be applied to mechanisms constructed in accordance with Letters Patent No. 384,893, issued January 19, 1888, to J. C. Cutcheon, which machines are duplex-that is, they are provided each with two molds, two jacks, and a common mechanism for operating the same simultaneously, so that when one sole is under pressure the other one is in 'a position to be removed from its jack and replaced by another. Inasmuch, however, as myautomatic mechanism when placed upon a duplex machine is applied in precisely the same manner to each half of the machine, so as to operate each jack-slide independently of the other, I have not thought it necessary to show both halves of the complete duplex machine, but have illustrated in the accompanying drawings one-half of a machine built substantially in accordance with the Outcheon Ipatent, showing also my automatic throw-out applied thereto. Y

In said drawings, Figure 1 is a central transverse section of one-half of a duplex beatingout machine, taken on the line mw in Eig. 3.V Fig. 2 is a horizontal section taken j ust above the jack-carrying slide and Alooking downward. Fig. 3 is a vertical section taken on the line y y of Fig. 1, looking fromthe rear of the machine.

The parts of the mechanism which move the jack. up and down beneath the mold are lettered to correspond with the same parts as shownin the Cutcheon patent, A being the framework of the machine; F, the table which carries the jack-supporting slide 1I; I-I, the jack, and I the mold. The table F is prosernl 110.617,744. yuv@ moan.)

vided with slides c', which run up and down on the guides D. It is moved up and down by means of a toggle mechanism consisting of the toggle-link M, pivoted at its upper end to Athe table and at. its lower end to the toggle-link N,which latter is pivoted to the framework of the machine and also to a link N2, the lower end of which is provided with a box h, which embraces the crank 7o of the shaft O. This shaft is provided at its outer end with a gear O', which meshes with the pinion O2 upon the driving-shaft I). Said driving-shaft is provided with a frictionwheel, driving-pulley and brake-shoe, and a treadle Q2, and cams operated thereby are used Ato start and stop the machine, all substantially as shown and described in the Cutcheon patent, to which reference is made for a fuller understanding of these parts, they forming no part of the present invention.

The Vjack-supporting slides and also the molds in sole-molding machines have heretofore been moved forward and back automatically by means of a pivoted lever connectedthereto, but so far as I am aware such levers have always been actuated by cams, which have proved to be expensive in construction and not wholly satisfactory in use. Such cam mechanisms are shown, for instance, in Patents N o. 347,429, dated August 17,1886, to D. Knox, and No. 352,760, dated November 16, 1886, to G. A. Knox, both for molding-machines. In my present improvement I provide a rocking arm 10, pivoted on a shaft l1, secured to the framework of the machine and operated when applied to the Cutcheon machine above described by means of a connecting-rod 12, pivoted at its one end to the arm 10 and at-its other end on a pivot which unites the links N and N2. When my improvement is applied to a machine in which the jack is not moved up and down by the free end of the arm 10, which is intended to operate the jack-slide II, must of course be IOO so connected therewith that the former when reciprocated will slide the latter forward and back without interfering with its up-anddown motion, and, furthermore, the connection must be such as to permit a proper clcar' ance between said jack and its mold I-that is to say, the jack must be moved vertically into contact with the mold and away from the same, and hence must be free from any lateral motion at and near the upward limit of its vertical motion. My preferred method of accomplishing these results consists in connecting the upper end of the arm 10 with the slide H by means of a rod 13, which is pivoted at its ends to said arm and slide and is preferably made adjustable as to its length, as by oppositely screw-threading the ends of its central section and providing nuts therefor on the two end sections. This of course provides for the independent up-and-down and lateral motions of the slide H, and for the purpose of effecting the proper clearance the connecting-rod 12 is so constructed as to be compressible and extensible lengthwise. This may be done, as shown, by passing a guiding-rod 14, secured to one section of the rod 12, through a collar 15, forming part of the other end section of the rod 12, the two end sections being held apart by the stout spring 16, surrounding the rod 14. The slide H is provided with a suitable stop, such as 17, arranged by engaging with the abutment 18, formed on the table F, to arrest the lateral movement of the slide H at such a point that the jack II will then be directly under the mold I.

The operation of the machine shown in the drawings is as follows: Considering the machine as shown in Fig. 1 with the jack raised to its highest point, it will be observed that the effect of starting the machine will be to draw the rear end of the link N downward. The upper end of the arm l0 obviously will be at the extreme limit of its movement to the right when the two pivots at the ends of the rod 12 and the pivot by which the link N is secured to the framework of 'the machine are in the same straight line. This extreme position will not be reached until the link N has been drawn slightlydownward, and hence during the first part of the revolution of the shaft O the spring 16 will be compressed, and the arm 10 and the slide H will consequently be held immovable until the pivot connecting the link N and the rod l2 is drawn downward below the straight line above referred to, thus allowing for the proper clearance of the jack H,which meanwhile has been drawn down away from the mold I. The continued downward motion of the link N as the crank 7c completes its first half-revolution results first in relieving the tension of the spring 16 and then in throwing the arm 10 and the slide H, with its jack H', forward into the position shown in dotted lines in Fig. 1, when the shoe may be removed from the jack and replaced by another. Of course when the shaft O is again revolved through the next half-revolution the motions just described are reversed and the machine is brought back into the position shown in full lines in Fig. 1. The spring 16 is ,arranged to be somewhat compressed when the parts are in the position shown in Fig. l, so as to thereby hold the slide H firmly in the position shown.

It will be seen that by means of my improvement I provide a very simple and efficient mechanism for automatically throwing in and out the jack-slide.. Although I have shown and described it as applied to a duplex machine, it is obvious that it is equally applicable to a non-duplex machine or to a singlesection machine, both well known in the art. Furthermore, I do not consider my improvements as limited to the employment of the specific means shown for connecting the arm -10 with the slide H nor to the particular arrangement of the parts shown for the purpose of obtaining the lost motion required for clearance. For example, the feature of longitudinal compressibility might be transferred from the rod 12 to the rod 13 without departing from the spirit of my invention.
